My file testbook.xls opens as testbook.xls:1 or testbook.xls:2 or
testbook.xls:3.
These all seem to be the same, but I only want one of them. I can hide or
unhide these multiple workbooks, but how do I remove two of them so that I
only have one?

I don't know how I caused this 3-in-1 situation. If I same the file as
test.xls, and reopen this file I still find I have :1, :2, and :3 copies of
the identical workbook. Is it possible that the file corrupted while being
transfered from another machine on a flashdrive? I use Excel2000.

Thanks,
